Build a pattern and explain it

Paper and large paper squares.

  1. Make a row with one square, then another with two, then another with three.
  2. Draw the next two rows before adding the squares.
  3. Count the total after each row and write the numbers in a table.
  4. Describe the rule in your own words. Ask someone to predict the next total.

Can you explain a number pattern using both a picture and words?
